Publication number: 20080207077Abstract: Methods of fabricating display backplanes in a roll-to-roll process are described. Branchless enable lines, branchless data lines, and pixel electrodes are patterned on a surface of a flexible substrate. The pixel electrodes may include electrode extensions used to form contacts for backplane transistors. The gate electrode of each transistor is provided by an enable line. The drain and source electrodes of the transistors are provided by the electrode extensions and data lines. The length of the electrode extensions may selected to be about three or more times the width of the enable lines to achieve relaxed alignment tolerance. Storage capacitors may be formed at the crossings of the enable lines and the pixel electrodes.Type: ApplicationFiled: February 26, 2007Publication date: August 28, 2008Inventor: Michael A. Haase

Publication number: 20080194166Abstract: A display element includes a light emitting unit that supplies light; and an angle converting unit including a reflection surface, an output surface, and a flat surface. The angle converting unit converts an angle of the light by reflecting the light toward the output surface. The light emitting unit is arranged in a matrix in two directions substantially perpendicular each other on a standard plane. An inequality 0?t?p(p?d?f)(tan?a)/(p+d?f) is satisfied, where t is a distance between the flat surface and the output surface, p is a pitch of the light emitting unit arranged in a predetermined direction, d is a length of the light emitting unit, f is a length of the flat surface, and ?a is an angle between the reflection surface and the standard plane.Type: ApplicationFiled: February 12, 2008Publication date: August 14, 2008Applicant: SEIKO EPSON CORPORATIONInventor: Taisuke Yamauchi
